Guilin Air Quality Assessment Based on the Method of Ranking Interval Numbers
摘要
Abstract
For the complexity of environmental air, the method of ranking interval numbers was used to analyze Guilin environmental air quality from 2003 to 2009 by three indexes SO2, NO2 and PM10. Single index order is used in the method of ranking interval numbers. As far as SO2 and NO2 are concerned, the air quality of Guilin in 2004 is the best; but for PM10, the air quality of Guilin in 2007 is the best. The comprehensive assessment results are found through calculating the fuzzy weight coefficients, the relative superiority matrix of the comprehensive interval numbers and the ranking vectors of three indexes SO2, NO2 and PM10. It is shown that the air quality of Guilin in 2004 is the best. The other years are 2008, 2003, 2007, 2005, 2006 and 2009.关键词
